As of: 2026-02

What 0.82 means

New Architecture only — Fabric + TurboModules + JSI are the only path; the legacy bridge and the interop layer are removed.
No newArchEnabled=false escape hatch in the default template.
Stricter view flattening — long lists get measurable wins.
Hermes improvements; debugging moves fully to CDP.

Migration reality (early 2026)

Libraries without new-arch support (some camera/map/webview minors) are hard blockers — check the community compat matrix first.
react-native-reanimated 4.x required; 3.x gesture workflows need the codemod.
Autolinking is stricter: config plugins mutating Podfile/gradle by string matching frequently break.

Testing advice

Migrate on a branch with a real device farm — emulator-only QA misses Fabric layout diffs (borders, shadows, absolute fill), the top post-migration bug class.
